Title: Valve operating control system in engine
Inventor: KOBAYASHI TOSHIKI
IPC: F01L1/344
Filed: 2001-10-24
Abstract: A pair of valve-timing controlling oil passages leading to a second valve-operating characteristic changing mechanism are defined in a lower camshaft holder, and a valve lift controlling oil passage leading to a first valve-operating characteristic changing mechanism is defined between the pair of valve-timing controlling oil passages in a mating surface of the lower camshaft holder with a cylinder head. In an area where the width of the valve lift controlling oil passage is reduced in order to avoid the interference with the valve-timing controlling oil passages, the depth of the valve lift controlling oil passage is larger than that in the other positions, whereby a sectional area of the oil passage is secured. Thus, the oil passages leading to the first and second mechanisms can be formed compact in a camshaft support member.

Title: Switching device and method for traffic policing over a network
Inventor: MUNSHI SANJAY
IPC: H04L12/56
Filed: 2000-06-09
Abstract: A flow of information over a network is controlled by a policing function placed at a data link layer of the network. For a full-duplex architecture, an accumulated count value for each packet of information received as input by a switching device is ascertained during a predetermined interval. The policin g function at a data link layer determines if the accumulated count value has exceeded an interval bit rate based on a transmission rate set by a traffic contract at a networking layer higher than the data link layer. In response to the accumulated count value exceeding the interval bit rate, the switching device sends a PAUSE frame to halt transmission of the information. The half - duplex architecture, collision based backpressure and carrier-sense backpressure techniques are used by the policing function for enforcement of  the traffic contracts.
